About Direct Fired Duct Heater

The unique features of the Heat Injector allows it to be applied as a Direct Gas-Fired Duct Heater for many different applications.  The clean buring characteristics of the burner with dedicated combustion blower injects heat without adding a load on the air moving device.  The applications where we have been able to apply the Heat Injector as a Direct Gas-fired Duct Heater

Applied the Heat Injector to the airflow for a green-house operation in Dallas, Tx to allow the airflow to be heated and dehumidified at the same time.

Applied heat to the recirculated airflow in a 20 year old paint curing chamber for Prime Coat that had been heated with wall mounted Infrared heat...they liked it so well they later modified their Top Coat. They used to struggle to get heat them to 12o°, now they can heat to 145 to more thoroughly cure.

The Heat Injector was mounted on top of the recirculated airflow for the Paint Drying Chambers and Plaster Mold Drying Chambers where the vapor and moisture laden air is exhausted. The Heat Injectors are sized to achieve the desired discharge temperatures.

The application of the Heat Injector with its unique features are further define in the US Patents; 7,360,534 and 9,459,022.

The energy efficient method 

The Patented Heat Injector System is the most energy efficient method to heat air. It uses a direct gas-fired burner with a dedicated combustion blower which allows the airflow to be adjustable and to reduce the load on the main airflow blower.

Heat Injector vs Traditional direct gas-fired

 When there is an airflow being created by a process where there is exhausted airflow, the Gas-fired duct heater can be used to inject sufficient heat to achieve the desired discharge temperature.

Design Configurations Available

The Heat Injector can be positioned in virtually any position around a duct. The module can handle the elements and can be installed on a duct to inject heat from the top down, bottom up, and side to center.

Recent Heat Injector Projects

We recently designed 2(1,000MBH) Heat Injector duct heaters for 2 steel drying chambers for plaster molds.(We designed the sheet metal structure too.)  For the same customer we also designed and built a 400MBH Heat Injectors duct heater for a paint drying chamber(Designed this sheet metal enclosure too.) The steel structures were able to fully erected using our assembly instruction. After the booths were build the Heat Injectors were able to be set in place and wired up.  With the Heat Injector being pre-tested and our facility, startup is always a breeze.

We also supplied another configuration of a 400MBH Heat Injector for a greenhouse that had a unique situation where the customer need to apply heat after a cooling coil in a unconventional way to an air handling system. We had to design a “bolt together” vestibule inside the air handler that forced air through the injector chamber of the Heat Injector, This concept moved that heated airflow straight into the main airflow blower to the greenhouse. The tomatoes have increased yields due to the warmer temperatures and carbon dioxide produced by recirculated the low PPM count of the Heat Injector.  This Heat Injector was designed with a 10ft plug in whip for the  main control panel to be mounted near the ground for easy personnel access.

The unique features of the Heat Injector allows it to be applied as a Direct Gas-Fired Duct Heater for many different applications.  The clean buring characteristics of the burner with dedicated combustion blower injects heat without adding a load on the air moving device.

Talk about EFFICIENCY!!

"We (like most) aren’t made of money... however we went with the Heat Injector (David Krupp). In the last month we have performed several treatments but 4 treatments were larger than 3000 sq ft. The unit we went with was able to heat 3,000+ sq.ft. without any issues, 2 of the homes had 3 different floors. This is a propane heater with a VERY powerful fan pushing the heat throughout the home. The value we have been able to receive from a unit like this, and deliver a 100% success rate with our customers, is an all around win! I am all around impressed with this unit. 40 lbs total usage of propane on a 3,107 sq.ft. home. Talk about EFFICIENCY!!"

Recipe for a moneymaker!

"With this system, you can get more work with it, because your costs are lower, so therefore your price can be lower than the competition. Add the fact that you don't break or melt things inside, I'd say that you have the recipe for a moneymaker! My machine has paid for itself 3 times over in just the first 9 months!"

An Extra-Ordinary Heater

‘’I have a Heat Injector System for almost 3 years now. It isn't a cheap system, but it works so well. I bought a cheap diesel unit heater from a friend because it was a great deal also. It's decent, but unless my Heat Injector is already on a job, I never use the diesel unit. Comparing them both, it isn't even close. If I add another heater to my arsenal, I'll add another Heat Injector. To me, if you're doing a lot of bed bug work, the price isn't a big issue. You'll make it back, and end up with an extraordinary heater in the process. It's so efficient, my propane costs are roughly $25 for a job at most."’’
